Radio Over IP

Accessibility and efficiency are the key parts of communication in any organization. Due to the propagation characteristic of radio waves in the VHF/UHF band, an otherwise perfect solution for terrestrial communication, a bridge interface is required to extend this communication beyond the horizon.

Wireless radios in the Very High Frequency (VHF) and Ultra High Frequency (UHF) band are widely used and are popular owing to their pervasive range and the benign propagation conditions. However, since their propagation is limited to region of up to few 10s of kilometers many times it is required to bridge/ attach the existing VHF/UHF radios with GSM or landline or IP and extend the communication ability beyond the horizon leveraging entire of the above mentioned infrastructure modes.

We offer a technology solution, developed indigenously and locally as a performance optimized option for such radio over IP bridges.

Any emergency radio network interfaced with such a redundant infrastructure communication mode will ensure that key personnel remain accessible at all times as well as will also prevent any deadlock/ un-availability of key personnel condition in times of requirement.



• Sites can be connected over wide geographical areas
• Co-ordinate among various wings/ radio nets through the common gateway
• 100% indigenous solution
• Retain existing radio infrastructure

The solution allows emergency workers to not only co-ordinate efficiently but also in areas of network (cellular) outage their own radio wireless network can be relied upon to relay communication over multiple interfaces.
